We had the displeasure of hitting a massive pothole on a rainy night last week, in the F20 up in the Bucks countryside.
Bearing in mind we were going uphill in a 40 zone, we heard a massive thud. What was scarier was that we didn't even see the hole, because the road was so shiny and wet in the dark.
We pulled over at the top of the hill and inspected the car. The tyres were all intact, on inspection, but when we got back on the road over 50 mph, we could feel a vibration in the car.
Took it to the dealer, expecting to hear we'd cracked a rim, or maybe a tie rod. Dealer calls at lunch, telling me we have 3 buckled wheels.

OUCH. Both passenger wheels, and the nearside front wheel are wrecked.
We're quoted £330 for the front wheels and £350 for the rear + VAT and fitting, plus something called 'rec kds and adjustments' <-- what's that?
I went back on Tuesday to take photos of the road, and unfortunately, the biggest holes on that stretch have already been patched. We don't live nearby, so I couldn't get up there sooner, but now I think we have a toughie trying to claim back from the council, because I can't tell the depth of the hole(s) before it was repaired.
In any case, I filmed a video walking from the base of the hill up to the spot where the section of pot holes are, and also took photos, where I was measuring the potholes (the biggest one was 36" long).
It obviously stinks to have such a massive repair bill on a 63 plate car, especially through no fault of our own.
We're hesitant to claiming on car insurance, we don't have alloy wheel insurance (not that this would be covered anyhow). Getting compensation from the council is the obvious route, but I couldn't help but notice an article mentioning that Bucks CC only paid out 2% of pothole claims last year. Nevertheless, we're writing a FOI request to find out about maintenance and repair to that road.
Sounds like FTH is my next calling point.
